PH 110.. WASHINGTON n c as AE FTC CULTIVATOR.

To all whom it may concern:

Be it known that I, LEONHARD'I SEssLER, a subject of the Emperor of Germany, and residing at Bottenweiler, near Zumhaus, in Bavaria, Germany, have invented certain new and useful Improvements in Cultivators, of which the following is a specification.

It is rather laborious and toilsome to work the furrowed soil if interspersed with loose, undecomposed stable dung, with the cultivators known up to now. In order to overcome the difficulties arising from this cause, I propose to substitute rotary cutting-disks or cutters for the resilient teeth at present in use, the object of these cutters being to cut up the said dung so as to allow of a proper working of the soil from the beginning. Some of the elastic teeth may, however, be retained if desired, and at any rate I prefer to make the said cutters adjustable, as is more fully described hereinafter.

The accompanying drawing shows, as an example, one form of construction of my improved cultivator, there being in this instance all the resilient teeth replaced by the rotary cutters in question.

Figure 1 is a side view of the machine, and Fig. 2 is a plan of the same.

The axles Z) which may be turned simultaneously and uniformly by means of a hand lever, as shown, are provided with resilient bars 0 secured to said axles by U-shaped double bows (Z. These bows may be shifted horizontally along the axles and the bars may be shifted vertically in the said bows so as thereby to adjust the tools carried by the bars horizontally as well as vertically, according to the nature of the soil to be treated.

The tools in question consist of the rotary cuttii'ig-disks g which may be individually adjusted at the bars a by U-shaped double bows c resembling closely the bows cl. The cutters g are held by axles f, preferably Specification of Letters Patent.

curved, and the bows e serve for attaching the said axles to the bars 0. The axles f may, therefore, be bodily adjusted toward or from the bars 0, and where curved axles are employed, the adjustment can be efiected also in regard to the angular position of the said rotary cutters. Furthermore, the cutters may be arranged either at the left hand side or the right hand side of the bars 0 (see Fig. 2) and thus the possibility is offered to symmetrically force the earth either in a direction to or away from the slopingsides of the furrow.

What I claim as new and desire to secure by Letters Patent is:

1. In a cultivator, the combination with a frame, of a rotary cutter, a bar adapted to be adjusted horizontally and vertically, a curved axle for carrying said cutter, and a clamp for adjustably securing said axle to said bar but permitting adjustment of said cutter toward or from said bar, substantially as and for the purpose set forth.

In a cultivator, the combination with the frame, of a rotary cutter, a bar carried by said frame, a curved axle for carrying said cutter, and a U-shaped double bow clamping said axle against said bar, for the purpose as described.

3. In a cultivator the combination with the frame, of straight axles adapted to be turned, elastic bars held by said axles, U- shaped double bows connecting the axles with the bars, curved axles held by the lat ter, other U-shaped bows connecting these axles with the said bars and rotary cuttingdisks supported by said curved axles, for the purpose as described.

In testimony whereof I affix my signature in presence of two witnesses.
